'Angels of God' in the Bible

for in the other life after this, there will be no such thing as marriage; but they will be as the angels of God in heaven.

moreover I declare unto you, whoever shall acknowledge me before men, him shall the son of man also own before the angels of God.

but whoever shall renounce me before men, he shall be renounc'd before the angels of God.

and he said to him, I declare unto you, hereafter you shall see heaven open, and the angels of God ascending, and descending upon the son of man.

and when he re-introduces the first-begotten into the world, he saith, " and let all the angels of God worship him."
